General information about the trial
|
|||
Main objective of the trial |
The purpose of the study is to establish the efficacy and safety of fixed-dose combination (FDC) of perindopril/amlodipine (Amlessa®) and fixed-dose combination of perindopril/indapamide/amlodipine (Co-Amlessa®) in wide populations of uncontrolled patients with arterial hypertension (AH) with special focus on effective continuous 24-hour blood pressure (BP) control. The purpose is also to establish the correlation between 24-hour central and peripheral BP.
|
||
Protection of trial subjects |
Patients had 3 main follow-up visits (visit 2, visit 3 and visit 4) and final visit (visit 5) at the end of the study. At each of the three follow-up visits, patient`s office blood pressure (BP) was measured. If normal office blood pressure (NBP - defined as SBP < 140 mmHg and DBP < 90 (85 for patients with type 2 diabetes mellitus) mmHg) was achieved, the patient continued treatment with the study medication prescribed. If NBP was not achieved, study medication dose was increased in order to achieve NBP and to protect the patient.
At visit 1 and visit 5, complete laboratory analysis (blood counts, clinical chemistry, liver enzymes, lipid measurements) was performed. To further protect the patients, on visits 2, 3 and 4 safety assessing laboratory analysis was performed.

Arm description |
In Amlessa arm were allocated antihypertensive medication naïve patients, patients on previous antihypertensive monotherapy and patients on previous dual antihypertensive therapy (based on the decision of the Investigator).

End point description |
Based on the blood pressure measured on visit 5, for each patient was determined if he reached NBP after 16 weeks of treatment with Amlessa or Co-Amlessa. NBP was defined as SBP < 140 mmHg and DBP < 90 mmHg (SBP < 140 mmHg and DBP < 85 mmHg for patients with type 2 diabetes mellitus). This end point display the proportion of all 440 patients in FAS population that has reached NBP after 16 weeks of treatment.

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: The inferential part of statistical analysis was based on two-sided confidence intervals. Two-sided “equal-tails” Clopper-Pearson exact 95%-confidence intervals were calculated to estimate the population proportion of patients meeting a particular target BP or target BP/PWV decrease endpoints. There was no comparison between groups for primary endpoint evaluation. Each treatment arm was evaluated for primary endpoint separately and whole FAS was evaluated for primary efficacy endpoint. |
